Method	Estimate	Interval
REML	0.083	(0.011, 0.633)
Gen Q ($a_i={\sigma }_i^{-2}$)	0.115	(0.003, 0.691)
Gen Q ($a_i={\sigma }_i^{-1}$)	0.261	(0.000, 1.125)
Paule-Mandel/Q profile	0.219	(0.002, 1.487)
Bayesian	0.135	(0.011, 0.495)

The REML confidence interval for τ² is approximate and the Bayesian estimate is the posterior mean.
